I'm surprised at the number of people who find Sunsingers to be underwhelming or only useful for self-res. Besides the build that I've shown here, there are multiple other configurations that either produce a lot of orbs or provide plenty of DPS. The touch of flame, viking funeral build with fusion grenades was shown to deliver more damage than Black Spindle, plus the viking funeral debuff can stack with tether or melting point. Then there's song of flame which if used with Praxic Fire, can provide significant cooldown speeds for you and others near you. Flame shield melee is still probably the best melee in the game, but brimstone and solar wind have very fast cooldowns, so you can essentially have a 5-5-5 build with a Sunsinger. In my opinion, one of the most flexible subclasses in the game, now.
